Solid Bottle Caps | Solvent Delivery Caps | Parts & Accessories

Mobile Phase Bottles are important for the proper upstream fluid delivery of any HPLC instrument. Keeping solvents clean of debris, prevention of atmospheric oxygen and CO2 absorption and evaporation of the more volatile solvent can be the difference between reproducible and non-reproducible results. The cap is important in protecting your mobile phase in the bottles. Most labs use these Bottle Caps to comply with their HPLC GLP requirements.

MicroSolv Mobile Phase Delivery Caps:

  • Have Inert, Medical Grade PTFE Liners

  • Allows Proper Venting

  • The Delivery Cap assembly can be autoclaved.

The Cap "insert" is made from medical grade PTFE protecting your mobile phase from plastic or wax film contamination. Keeping these caps on the bottles with tubing threaded through the holes prevents dust and dirt from getting in and minimizes outgassing or absorption of CO2 from the atmosphere.
